The activity of glucose-6-phosphate dehydrogenase (G-6-P-DH; D-glucose 6-phosphate: NADP oxidoreductase, EC 1.1.1.49) in leaf extracts of barley and spinach can be decreased 20-35% by incubation of the leaf extracts with dithiothreitol (DTT). This inhibition is complete within 2 min at 0°C and is reversible. The DTT-inhibited portion of G-6-P-DH activity in leaf extracts is probably that portion of leaf enzyme inhibited during illumination, and evidence has been obtained that this activity is located in the chloroplasts.
葡萄糖-6-磷酸脱氢酶（G-6-P-DH；D-葡萄糖 6-磷酸：NADP 氧化还原酶，EC 1.1.1.49）在大麦和菠菜叶提取物中的活性可被二硫苏糖醇（DTT）降低 20-35%。这种抑制在 0°C 下 2 分钟内完全，并且是可逆的。叶提取物中 G-6-P-DH 活性的 DTT 抑制部分可能是在光照期间被抑制的叶酶部分，并且已经获得了该活性位于叶绿体中的证据。
